Description
A nourishing, protective conditioner that helps shield hair from daily damage to help maintain hair health and improve smoothness and shine. Engineered to weightlessly soften and detangle while the K18PEPTIDE™ helps replenish hair during washing.

Get started here
The mask and conditioner serve two different purposes. The K18 mask reverses damage in 4 minutes, while the K18 conditioner protects hair from daily damage for up to 3 days*. We recommend using the K18 mask first, waiting 4 minutes, then using conditioner for additional softening and detangling benefits between K18 mask days.
*Disclaimers
No, the K18 conditioner will not cause buildup on hair. The highly concentrated, lightweight gel formula means a little goes a long way. Use less than you typically would with a traditional conditioner, and build as needed.
No, the K18 conditioner will not weigh hair down. This highly concentrated, lightweight gel formula softens, smooths, and detangles without film-forming silicones or waxes that can build up over time.
No, you do not need to reapply the K18 conditioner for continued UV protection. This product is clinically proven to protect hair against damage from UV rays for up to 3 days*.
*Disclaimers
No, the K18 conditioner does not have SPF. The biotech-produced polysaccharide and fortifying ceramide blend help minimize the drying and damaging effects of UV rays on the hair's cuticle. This prevents hair from becoming rough, brittle, weak, and prone to breakage from UV damage for up to 3 days*.
*Disclaimers
3-day damage protection, powered by biotech

Love the products but HARD to get out of bottles!
Love the products but HARD to get out of bottles!
Love the K18 products but it’s Really Hard to squeeze the liquids out of the HARD plastic bottles! I have to use my teeth! and the force of my jaw to get the liquid to come out. My fingers aren’t that strong, and hands are wet of course, so I can’t get any force behind my fingers to get the bottles to bend easily when I try to squeeze!! Please reconsider your packaging to make it easier to dispense your great products! TY

Highly Recommend
I have been using the K18 Pro Mist and Molecular Mask for about 4 years now…….both quickly became a mandatory part of all of my color services.
I recommend the Damage Shield duo to anyone who doesn’t want to spend a lot of time on their hair. Unfortunately, the reality is that many clients don’t use color safe products or heat protection on their hair….. this is a “no brainer”, because it does all of the above. …… and has an attractive price point.
